ABSTRACT:
A bent tubular profile with lateral grooves intended to form arches for a covering-structure which may be removed is presented. The covering-structures may be at least partially removed between each of the pairs of arches thereof by sliding flexible sheets which are preferable made from a plastic material which is generally transparent. The arch is formed by a single-piece bent profile comprising a central bearing body which is tubular and has a round, oval, square, rectangular or polygonal section or is a U-shaped profile. Bearing on each side and perpendicularly to its vertical plane of symmetry are fins arranged one above the other. The device of the present invention is more particularly intended for covering a swimming pool.
